The more people sign each other keys, the stronger the decentralised chain of trust becomes for people to be able to send emails to each other, even without having been in the same room as each other.
Come with your key, laptop and/or phone and let's sign each other's key and then upload the signatures on the global internets \o/
There will be guides for the people who have never signed keys before to help them do it :-)
